6 Claims. (Cl. 31-169) This invention relates to ground working imon alevel somewhat above the center of depth plements, and particularly toground leveling of the unit. or check and border'forming implements.Radial arms l are rigid with the shaft at its When leveling ground, itis necessary that the ends, and lie in transverse planes just outsidesupporting wheels of the leveler blade unit shall .the sides of theunit. The arms at their outer be behind and disposed in planes inwardlyof 'ends are provided on opposite sides with enlarged the side edges ofthe blade, in order that the disc-like flanges 8, the outer faces ofwhich are wheels will rest at the level of the blade. On adapted toalternately engage a disc 9 of correthe other hand, for check or borderforming sponding size and to be removably secured there- 10 purposes,the wheels must lie in planes outwardly against by bolts I0 (see Fig.2).

unit, and support a transverse shaft 6, located Such swinging of arm I3is imparted thereto in 55 either direction, depending on the normalposition of arm l3 as above stated, by means of a hydraulic cylinder l8.This extends along beam 3 and is adjustably engaged by a clamping collarl9 having side trunnions 20 turnable in brackets 2| on beam 3. A piston22 in the cylinder is connected to a piston rod 23 which projects fromthe rear end of the cylinder and is connected to arm l3. Supply pipes 24lead to both ends of the cylinder so that fluid may be fed to thecylinder to move the piston one way or the other.

Thecylinder is disposed so that when the blade is in digging positionfor leveling, the piston is adjacent the forward end of the cylinder, asindicated in'Fig. 3. When the blade is in a digging position forchecking, th'episton is at the rear end of the cylinder as shown in Fig.1; the digging depth being positively limited, as is then desirable, byshifting the cylinder in its supporting collar l9 so that the pistonabuts against the rear end of the cylinder when the blade is set to cutat the desired depth.

To change the setting of the parts for one use or the other of theimplement, it is only necessary to reverse the position of the wheelsrelative to arms I, by removing and then replacing bolts ill. The boltsii are then' withdrawn, andthe arms '1 swung from one position to theother. The arm I3 is then turned to the corresponding position, and thebolts l6 passed through the other pair of holes l5 and said'arm l3. 1

The wheels being ahead of the shaft 6 and the blade when in checkingposition, a great vertical movement of the blade is had with arelatively slight turning of the shaft, so that dumping may be effectedvery rapidly as is desirable when checking.

From the foregoing description it will bereadily seen that I haveproduced such a device as substantially fulfills the objects of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful anddesire to secure by Letters Patent is:

1. A ground working implement including a scraping blade, rearwardlyprojecting side arms pivoted at their forward end in permanentlysupported connection with the blade, a pair of wheels and exposed meansto mount the wheels on the outer end of the arms laterally out from thesame in transverse planes clear of the side edges of the blade andlaterally in from said arms in transverse planes between the side edgesof the blade,

selectively. v 7 2. A structure as in claim 1, in which said wheelmounting means comprises, for each wheel,a stub axle, a vertical discfrom which the axle projects, plate elements on the outer end of the armon opposite sides thereof and against either of which the disc isadapted to abut and bolts removably securing the disc and a plateelement together.

3. A ground working implement including a scraping blade, rearwardlyprojecting side arms pivoted at their forward end in supportedconnection with the blade, said arms being disposed in transverse planesclosely adjacent but laterally out from the side edges of the blade anda pair of wheels, one for each arm, and means to mount each wheel onopposite sides of an arm on the outer end thereof selectively.

4. A ground working implement comprising a scraping blade, a transverseshaft mounted above the blade in supported connection therewith, sidearms disposed laterally out from the side edges of the blade rigid withand extending radially from the shaft, the 'shaft beingturnable wherebythe arms may extend rearwardly or forwardly of the shaft, a pair ofwheels, one for each arm, and

means to reversibly mount the wheels on the outer end of the arms onopposite sides thereof selectively.

'5. A ground working implement comprising a scraping blade, a transverseshaft mounted above the blade in supported connection therewith, sidearms disposed laterally out from the side edges of the blade mountedrigid with and extending radially from the shaft, the shaft beingturnable whereby the arms may extend rearwardly or forwardly of theshaft, a pair of wheels, one for each arm, mounted on the outer end ofthe arms and means to control the rotation of the shaft when the armsare in either position; such control means including an arm projectingradially from the shaft, and means to secure said last named arm indifferent relative positions circumferentially of the shaft whereby saidarm will upstand from the shaft irrespective of the setting of the sidearms.

6. A ground working implement comprising a scraping blade, atransverse'shaftmounted above the blade in supported connectiontherewith, side arms disposed laterally out from the side edges of theblade mounted rigid with and extending radially from the shaft, theshaft being turnable whereby the arms may extend rearwardly or forwardlyof the shaft, a pair of wheels, one for each arm, mounted on the outerend of the arms and means to control the rotation of the shaft whenthearms are in either position; such control means including an armprojecting radially from and initially turnable on the shaft, ahydraulic cylinder mounted on the implement and having a piston rod"projecting therefrom and connected'to said last named arm, means tosupply fluid to both ends of the cylinder and means to releasably securethe last named arm on the shaft in such position relative to the sidearms and to the cylinder that when the side arms are rearwardly disposedand the blade is in digging position, the piston rod is retracted in thecylinder and when the side arms are'forwardly disposed and the blade isin diggingposition, the piston rod is advanced from the cylinder.
